Nick Hewer and Margaret Mountford explore the impact of immigration in the UK by bringing both sides of the debate together. Pairing five Brits who are opposed to immigration with five immigrants, they look at the issues of jobs, housing and what it means to be British.

Nick Hewer and Margaret Mountford return with the second part of their social experiment. The UK-born citizens discover the impact the immigrants have on public services like schools and the NHS before deciding whether they are a 'gain' or 'drain' on Britain.
